2 More Journalists Go Missing in Colombia

While security forces searched for a missing Spanish journalist in Colombia, two more journalists were reported missing Tuesday in the same region.

The two journalists from the right-leaning TV network RCN had traveled to the Catatumbo region to cover the hunt for Salud Hernandez-Mora, a longtime correspondent for the Spanish newspaper El Mundo whose weekly column in the Bogota daily El Tiempo is one of the most read in Colombia.

Authorities declined to call Hernandez-Mora's disappearance a kidnapping, and no one had claimed responsibility for her disappearance, but speculation heightened that she could have been taken hostage by the rebel National Liberation Army, the ELN. It is one of several armed groups and drug trafficking gangs dominant in the mountainous area bordering Venezuela.

Journalists from the Spanish news agency EFE and local network Caracol were detained briefly by armed men Monday covering the search. Diego Velosa from Caracol said he was stopped by a group identifying themselves as members of the ELN and forced to hand over equipment during a tense standoff that lasted a few hours. He said he was told by his captors that they were also holding RCN journalist Diego D'Pablos and his cameraman Carlos Melo.

Hernandez-Mora had not been seen or heard from since Saturday, when she was spotted arguing with an unidentified man and then hiring a motorcycle to take her to an unknown destination.

Pressure was mounting on President Juan Manuel Santos, who is struggling to maintain support for peace talks with the Colombia's two rebel groups, who Colombians overwhelmingly despise. On Tuesday, he ordered the head of the police and army to travel to Catatumbo to oversee the search.

Gen. Alberto Mejia, the army chief, said security forces face a steep challenge.

"We're not talking about a soccer field, we're talking about one of the most-difficult regions for the armed forces to operate," Mejia said at a news conference.

The Jamaica-sized region of northeastern Colombia is among the country's poorest, most marginalized backwaters. It is a major coca-growing area and corridor for cocaine smuggling to Venezuela, with the state able to maintain only a few militarized strongholds.

The region was home to a ruthless cocaine warlord and ex-rebel nicknamed "Megateo," until security forces finally tracked him down last year and killed him in an airstrike. Remnants of his Popular Liberation Army are still active in the area as is the ELN and the country's main rebel movement, the Revolutionary Armed Forces of Colombia, the FARC.
